It is not recommended.
No , they operate at different pressures and are not compatible.
Not unless you like the idea of destroying your AC system.
No, you should not mix R22 and R22a refrigerants together. Mixing different refrigerants can lead to system inefficiency, reduced cooling capacity, and potential damage to the equipment. It is important to use the correct refrigerant specified by the manufacturer for your system.
No the whole system need to be evacuated of the r22 before you put r22a in the system. It's against the law to mix 2 different freons together and also dangerous.
Absolutely not ... R410 operates at much higher pressures than R22, and mixing would do nothing but contaminate both refrigerants (and possibly mess up your system)
Mixing R22 refrigerant with R438A is not recommended. R438A is a replacement for R22, but it has a different composition and properties. Mixing refrigerants can lead to reduced efficiency, potential equipment damage, and difficulty in servicing the system. It's best to fully evacuate the system and charge it with the appropriate refrigerant.
